Joahaz was twenty-three years old when he became king of Judah, and he ruled in Jerusalem for three months. His mother was Hamutal, the daughter of Jeremiah from the city of Libnah.
Following the example of his ancestors, he sinned against the Lord.
His reign ended when King Neco of Egypt took him prisoner in Riblah, in the land of Hamath, and made Judah pay 7,500 pounds of silver and 75 pounds of gold as tribute.
King Neco made Josiah's son Eliakim king of Judah as successor to Josiah, and changed his name to Jehoiakim. Joahaz was taken to Egypt by King Neco, and there he died. 1
